89728 RS-232/422 Plenum Cable - 4 Pair Individually Shielded

The Belden 89728 delivers individually shielded pairs with plenum fire safety for RS-232/422 and digital audio applications in air handling spaces. Four pairs of 24 AWG stranded tinned copper conductors in a 7x32 construction provide isolated channels where crosstalk between circuits cannot be tolerated.

Individual Beldfoil® shielding on each pair with 100% coverage and dedicated 24 AWG stranded tinned copper drain wires ensures complete isolation between adjacent pairs. Foam FEP insulation contributes ultra-low capacitance for extended cable runs and high data rates while supporting the plenum rating.

The fluorocopolymer outer jacket meets CMP plenum requirements for installation above drop ceilings and below raised floors. The 100 ohm impedance suits balanced digital transmission. The 89728 serves broadcast facilities, data centers, and commercial buildings requiring plenum-rated individually shielded data cabling.
